Iran Drought 2025: Tehran Faces Severe Water Crisis as Reservoirs Near Empty

Published: November 10, 2025

Introduction

Iran is grappling with an exceptional drought in 2025, severely impacting Tehran and marking one of the worst water shortages in recent history. With rainfall at record lows this fall, reservoirs supplying the capital are critically depleted, prompting urgent calls for water conservation. President Masoud Pezeshkian has highlighted the risk of rationing and even evacuation if conditions persist, underscoring the gravity of the Tehran water crisis. This article breaks down the causes, effects, and responses to help readers understand this unfolding environmental challenge.

Analysis

The Iran drought 2025 stems from prolonged low precipitation, aging infrastructure, and external factors like recent military conflicts. Meteorological data confirms no significant rainfall expected for the next 10 days, exacerbating the situation.

Reservoir Depletion in Tehran

Key water sources for Tehran, including the Latian Dam and Karaj Dam, are operating at under 10% capacity. Mohammad-Ali Moallem, head of the Karaj Dam, reported a 92% rainfall drop compared to the previous year, leaving only 8% usable water—much of it classified as “dead water” unfit for supply.

Official Warnings and Responses

Energy Minister Abbas Ali Abadi warned of potential complete water flow cuts at night, while announcing penalties for excessive consumption by households and businesses. President Pezeshkian emphasized that rationing alone might not suffice, raising the possibility of evacuating Tehran—a statement met with criticism from figures like former mayor Gholamhossein Karbaschi, who dismissed it as impractical.

Broader Regional Impact

Beyond Tehran, provinces like West Azerbaijan, East Azerbaijan, Markazi, and Khorasan Razavi face similar woes. In Mashhad, Iran’s second-largest city, dam storage has fallen below 3% in major facilities like Torogh, Kardeh, Doosti, and Ardak, with only Doosti partially operational. Governor of Khorasan Razavi described it as a “mega-challenge of drought.”

Contributing Factors

Ali Abadi attributed part of the crisis to water leaks from Tehran’s century-old pipes and damage from a 12-day conflict with Israel in June, including a strike on the Tajrish neighborhood that caused localized flooding and infrastructure strain.

Summary

In summary, the Tehran water shortage in 2025 reflects a perfect storm of minimal rainfall, over-reliance on dwindling reservoirs, and infrastructural vulnerabilities. Daily life is disrupted, with residents resorting to bottled water and tankers. Officials urge conservation amid bleak forecasts, while long-term mismanagement amplifies the water disaster in Iran.

Key Points

Practical Advice

To combat the Iran water crisis, individuals and communities can adopt proven conservation techniques. These strategies, recommended by water management experts, reduce demand and preserve limited supplies.

Household Water Saving Tips

Fix leaks immediately—dripping faucets waste up to 20 liters daily. Install low-flow showerheads and toilets to cut usage by 50%. Reuse greywater from sinks for irrigation. Limit showers to 5 minutes and turn off taps while brushing teeth.

Business and Community Measures

Businesses should audit usage and switch to efficient appliances. Communities can organize collection drives for rainwater harvesting, where feasible. In urban settings like Tehran, prioritize public awareness campaigns to monitor consumption meters daily.

Long-Term Urban Strategies

Pedagogically, understanding hydrology helps: Promote desalination pilots and wastewater recycling, as seen in successful arid-region models. Track personal usage via apps to stay under daily quotas, typically 150 liters per person in crisis zones.

Points of Caution

While addressing the exceptional drought in Iran, caution against health and safety risks is essential. Prolonged water shortages increase dehydration risks, especially for vulnerable groups like the elderly and children. Contaminated “dead water” from reservoirs poses hygiene threats, potentially leading to gastrointestinal issues.

Social and Economic Warnings

Evacuation rhetoric, though controversial, signals extreme measures—residents should prepare emergency kits with bottled water (at least 3 liters per person daily for 72 hours). Avoid panic buying, which strains supplies further. Monitor official updates from Iran’s National Centre for Climate and Drought Crisis Management to verify forecasts.

Comparison

Comparing the 2025 crisis to prior years highlights escalation. Last year saw 92% less rain, but reservoirs held more viable water. Tehran (population ~9 million) contrasts with Mashhad (~3 million), where dams are even lower (3% vs. Tehran’s 8-10%). Nationally, over 16 million in Tehran, Karaj, and Mashhad face taps running dry, worse than 2011 warnings.

Regional vs. Global Drought Benchmarks

Iran’s single-digit reservoir levels mirror severe cases like California’s 2014 drought (40% below average) but exceed in urban density impact. Unlike Saudi Arabia’s desalination reliance, Iran’s dams remain primary, amplifying vulnerability.

Legal Implications

Iranian authorities have introduced enforceable measures for the water shortage in Tehran. Energy Minister Abbas Ali Abadi announced penalties for households and businesses exceeding consumption limits, likely including fines or service cuts. These align with existing national water laws prioritizing equitable distribution during crises. Non-compliance could result in legal notices, enforceable under Iran’s environmental regulations. Residents should review local guidelines to avoid violations.

Conclusion

The Iran drought 2025 and Tehran water crisis demand immediate collective action. From presidential alerts to resident adaptations, the path forward involves conservation, infrastructure upgrades, and rainfall dependence. By learning from this water disaster, Iran can mitigate future risks, ensuring sustainable supplies for its urban centers. Stay informed and conserve—every drop counts.
